IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 203,421, dated May '7,1878; application led April 15, 1878.

To all whom it may concern:

Be it known that I, SHERMAN M. COLE, of Anamosa, inthe county of Jones,and in the State of Iowa, have invented certain new and usefulImprovements in Pumps; and do hereby declare that the following is afull,-clear, and exact description thereof, reference being had to theaccompanying drawing, andto the letters of reference marked thereon,making a part of thisspeciication. V

The nature of my invention consists in the construction and arrangementof an oscillatifng Ipump, as will be hereinafter more fully set ort Inorder to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure lis a side view, partly in section, of my pump. Figs. 2, 3, and 4are detailed views of parts of the pump.

A and B represent two casings, forming,

when put together, the horizontal pump-cylinder, and in the jointbetween the two casin gs is inserted a disk, C, which forms a divisionbe-' tween them. Around this disk is placed suitable rubber packing a,as shown, and when the two casings or chambers are fastened together itforms a water-tight joint between them. The two casings are connectedtogether by rods b b,

y which hook into eyes e c, and these eyes are adjusted and the hookedrods drawn tight by thumbnuts d d, as shown in Fig. l. The chamber Bis,at the top, provided with the outlet E, and ,at the bottom there aretwo valves, D D, opening into said chamber from the chamber A. Thesevalve-openings are located, one on each side of an abutment orpartition,F running the entire length of the chamber A, from the center verticallydownward to the bottom, and on each side of this abutment, at the'bottomof the casing, is a valve, G, for opening and closing the inlets to `thechamber A. Centrally through the chamberA is passed a horizontal shaft,h, to the outer end of which a pulley or other device, H, is attached,for applying` power to the pump in any suitable or convenient manner. Tothis shaft h is secured a wing, I, which extends the entire length ofthe chamber A, and has suitable packing i all around its edges on bothsides. The wing I is rotated from one side to the other, and

vice versa, drawing in the water behind it, and' forcing that ahead ofit, through the corresponding valve D, into the chamber B, and outthrough the exit E.

The pump is intended to be submerged in the well, and is easilyoperated.

The construction of the pump is such that it can be cheaply made, andcan easily and quickly be taken apart when require-d to renew thepacking.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the casin gs or chambers A B, with interposeddiskl G and rubber packing a., the hooked rods b, eyes c, and thumbnutsd, as and for the purposes herein set forth.

2. The combination of the chambers A B, disk C, with valves D D,abutment F, valves Gr G, and shaft h, with wing I, all constructed andarranged'lto operate substantially as and for the purposes herein setforth.

In testimony that I claim the foregoing I have hereunto set my hand this2d day of April, 187 8.
